澳大利亚四足动物类群物种的地理分布范围大小呈“空心曲线”频率分布，多数物种的分布范围较小。范围大小的几何平均值（以10（5）平方公里为单位）为：青蛙和蟾蜍1.2，海龟1.7，蜥蜴2.2，蛇3.2，鸟类6.6，有袋动物2.6，蝙蝠5.1，啮齿动物2.1。对不同类群的物种密度进行了比较。哺乳动物的重叠物种边界图显示了一些相对同质的动物区，它们被明显而狭窄的动物区系边界分隔开，但这不是一般的模式。许多类群物种分布区的主轴与海岸平行或靠近海岸。集中在内部的物种往往有更大的范围。如果有更多的已发表的记录、标本、已知的发生地点和生态学数据，对分布区大小的估计或测量往往会更好。澳大利亚的无尾目动物、蜥蜴（和其他爬行动物）和有袋类动物比北美多，啮齿动物和蝙蝠比北美少。两个大陆的平均活动范围大小的排序是相同的，除了无尾目蜥蜴的活动范围比澳大利亚的蜥蜴小。
The sizes of geographic ranges of species of Australian tetrapod groups form 'hollow curve' frequency distributions, with most species having small ranges. Geometric means for range size (in 10(5) km2 units) are 1.2 for frogs and toads, 1.7 for turtles, 2.2 for lizards, 3.2 for snakes, 6.6 for birds, 2.6 for marsupials, 5.1 for bats and 2.1 for rodents. Species' densities are compared for different groups. A map of superimposed species boundaries for mammals demonstrates some relatively homogeneous faunal areas separated by distinct and narrow faunal boundaries but this is not the general pattern. The principal axes of species ranges for many groups are oriented parallel to and near coasts. Species centred on the interior tend to have larger ranges. Estimates or measurements of range size tend to be better if there are more published records, specimens, known localities of occurrence, and ecological data. Australia, in proportion to its area, has more anurans, lizards (and other reptiles), and marsupials, and it has fewer rodents and bats than North America. The ranking of groups for mean range size is the same in both continents except that Anura have smaller ranges than lizards in Australia.
